Power fuel tank cover for automobiles

A power fuel tank cover comprising:

• a motor;
• a collar having a circular member and a tubular member formed at one side thereof, said tubular member being formed with a hole which is in communication with an opening of the circular member;
• a worm rod inserted into the tubular member of said collar;
• a sleeve fitted into said collar;
• a worm gear mounted on said sleeve and engaged with said worm rod, said worm gear having a center hole with internal threads;
• an actuating cylinder with external threads being engaged with the center hole of said worm gear;
• a lid pivotally connected with an upper portion of said actuating cylinder and having a seat with a groove at a bottom, a positioning plate on a top and a hole extending through said seat and said positioning plate for receiving a ball, a plug, and a spring, said positioning plate extending outward to form a block;
• a connecting member pivotally connected between said collar and said lid;
• and
• a press plate threadedly engaged with the positioning plate by a screw connected with a linking rod via a ring which is in turn connected with a fixing plate, said fixing plate being designed to engage with a fuel tank cover;
• wherein the motor, when activated, rotates an axle connected to a cable which in turn rotates the worm rod, causing the worm gear to activate the actuating cylinder, thus urging the lid to a position perpendicular to the collar, thereby causing the fuel tank cover, to open inasmuch as the lid is connected to the fuel tank cover via the fixing plate and the linking rod.
